Abstract
A simple method for determination of metrafenone in vegetables by matrix solid-phase dispersion (MSPD) and HPLC was developed. All vegetable samples were extracted with dichloromethane, and then the extracts were directly separated on a reversed-phase column with isocratic elution without a cleanup step. The linearity of metrafenone was good with the concentration between 0.005 and 5 mg/kg, and the limit of detection (LOD) of the metrafenone was 0.002 mg/kg. The recoveries ranged from 86.5% to 104.8% with the relative standard deviations (RSDs) in the range of 2.1-7.9% (n = 6). The results indicated that the method was simple, rapid, highly sensitive and suitable for the determination of metrafenone in vegetables.
